7.5/10 used it for a long time, good for chain stabs by tricking enemies, (yes, casual is that stupid) if you don't want to use big earner for any of the various possible reasons.
But I also kind of used it for the handicap to troll people.

6/10 I personally only play soldier for rocket jumping, but I never use the direct hit as you need to be able to be a good aim with it as well as its reduced aoe effect, therefore making it difficult for players to use with lag/shitty computers.
